Containers from Scratch

This repo contains the exercises and demo code for a Containers from Scratch presentation (slides).

Getting Started

To follow along with this demo:

1. Clone this repo
2. Install Vagrant w/ Virtualbox support; tested w/ Vagrant 1.8.5
3. run bootstrap.sh # will install an Ubuntu 16.04.2 Vagrant box
4. run vagrant up
5. follow steps in demo.sh #almost, but not quite runnable

Note: The Vagrant VM provider is Virtualbox. If you need to use a different provider you can:

• switch provider to, e.g. VMWare, Hyper-V
• provision an Ubuntu 16.04 host by other means and then run the commands in provision.sh

Inspiration

This presentation is inspired by these truly excellent presentations:

• Jerome Petazzoni at DockerCon EU 2015
  • these exercises are a literal port of the closing demo from Jerome's talk
• Liz Rice's Containers From Scratch (golang)
